一种用于星载SAR天线的转动控制技术
Rotation Control Technique Applied to Satellite-Borne SAR Antenna
摘要
Abstract
In order to achieve an ultra-smooth motion profile under ultra-low speed condition for SAR Antenna and to meet the requirements for miniaturization,a rotation control technique for the Antenna Rotation,which uses two complete H-Bridge hybrid with internal PWM circuitry to drive a mixed stepper motor through microstep mode,is presented. Based on the detailed introduction of the system architecture and the microstepping control principle,the concrete measures of reliability design are also given. After test and environmental verification, the design can achieve smooth rotation at ultra-low speed and meet the requirements of space technology,so it has certain reference value for the similar application.关键词
